生物學特性     字彙 (例如 epibenthic)

Obligate air-breathing (Ref. 126274); Found in ponds, swamps, brackish water (Ref. 6028), ditches and beels (Ref. 1479). Adults prefer stagnant waters in muddy streams (Ref. 4833). Feed on worms, insects and small fish (Ref. 6028). Accept chopped fish and shrimp in the aquarium. Breed throughout the year. Mitochondrial hypertrophy, noted in the double cone of the retina of this species, is considered a basic process in oil droplet formation (Ref. 10557) believed to be an adaptation for enhanced visual contrast detection in turbid waters (Ref. 10407). Used as live bait for angling larger snakeheads.

發現於池塘,沼澤,半淡鹹水 (參考文獻 6028) ,溝渠與 beels了。 (參考文獻 1479) 偏愛泥濘的溪流的污濁的水域。 (參考文獻 4833) 吃蠕蟲,昆蟲與小魚。 (參考文獻 6028) 在水族館接受剁碎魚與蝦。 全年繁殖。 線粒體肥大,在兩倍這一個種的視網膜的圓錐體中被記錄到, 一般認為油小滴形成 (參考文獻 10557) 的一個基本的突起相信是混濁的水域的可提高的視覺差別發現的一個適應。 (參考文獻 10407) 被當作活餌使用對於釣魚更大的 snakehead。

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

Spawning usually takes place at night in shallow water with a silty substrate. Eggs are laid in nests through elaborate tunnels in vegetated areas which look like vertical columns of water with the eggs floating in the center (Ref. 205). The male and female move towards the center of the nest during spawning where the male entwines his body to the female moving upward while releasing the eggs to be fertilised (Ref. 45309). Eggs are guarded by one or both parents. Hatching takes place in a day (Ref. 6028).亞洲: 阿富汗,巴基斯坦,印度,斯里蘭卡,尼泊爾,孟加拉,緬甸與中國雲南。
